2AW3 ネマチック液晶欠陥の格子状配列(2015年奨励賞受賞講演,2015年日本液晶学会討論会)

抄録

Pattern formation in liquid crystals is an interesting topicof research. We explore an unconventional schlieren texture of nematic liquid crystals with negative dielectric anisotropy. It is found that the umbilical defects form a square array on a fluorinated polymer surface by applying a moderate electric field. The area of the defects array can be expanded by the self-organization nature or by an optical manipulation technique. We show that the system is highly tunable by several external controls.
